This paper deals with new-type dynamic vibration absorber for structures such as piping systems, buildings and towers. This dynamic absorber consists of balls and ball cases. It makes use of ball rotation for reducing the vibration of structures. The characteristics are shown as follows: (1) It is simple composition composed of some balls and ball cases and so it is low-cost type; (2) The frequency tuning is unnecessary, and so a preliminary measurement for adjustment is not necessary; (3) It is possible to correspond to any frequency without tuning ; (4) It is compact and easy to install on structures. We applied this self-tuning dynamic absorber to a pipe branch of piping system and a view tower as a large structure. The effects of vibration reduction were evaluated by simulation analysis and vibration test using a shaking table.
